Possible disable sound from internal speaekrs?

Hi Guys,
I have a strange request I need to disable sound from the internal speakers. I wanted to ask if this was possible?
Thanks
Berry

I've tried that by muting the output in system preferences. But it can be unmuted via the keyboard. I need to be able ti disable the internal speaekrs indefinitely. Is there a hack or a preference that I can get rid of?
There's also no alternative output device.
Thanks for the reply though.

There are many possible causes for this issue. Take each of the following steps that you haven't already tried. Some may not apply to your model. Back up all data before making any changes.
1. Start with the steps recommended in this support article. Don't skip any of the steps. It's the starting point for further efforts to solve the problem.
2. Run Software Update and make sure you have a fully up-to-date installation of OS X.
3. If you've installed an application called "Memory Clean" or any other third-party software that is supposed to "clean" or "purge" memory automatically, remove it according to the developer's instructions and restart. You should do that even if the software is not causing the problem, because it's useless.
4. Other third-party software that has been reported to interfere with sound output includes "Boom" and "Samsung Kies." If applicable, uninstall according to the developer's instructions (not by dragging something to the Trash.)
5. If an AirPlay device is selected for sound output from iTunes (or from other applications via third-party software such as "Airfoil"), deselect it.
6. Launch the application "Audio MIDI Setup" by entering the first few letters of its name in a Spotlight search and selecting it in the results (it should be at the top.) Select Built-in Output from the list on the left. If the Mute boxes are checked, uncheck them.
7. If a red light is visible in the audio-out port when sound should be playing, the internal switch is stuck in the position for digital output. You may be able to free it by inserting and removing a mini-stereo jack of the proper size. Inserting any kind of tool in the port may cause damage that won't be covered by your warranty.
If there's no red light, the switch may still be stuck in the headphone position. Try to free it the same way.
8. Disconnect all wired peripherals except keyboard and mouse, if applicable. If more than one display is connected, disconnect all extra ones. Restart and test.
9. If you have a MacBook Air, turn off Bluetooth and restart.
10. Start up in safe mode. Don't log in; just restart as usual when the login screen appears. When you do, make sure the words "Safe Boot" do not appear in the login screen. If they do, the system is still in safe mode and sound won't work.
11. Reset the NVRAM.
12. Reset the SMC.
13. Triple-click anywhere in the line below on this page to select it:
/Library/Preferences/Audio
Right-click or control-click the highlighted line and select
Services ▹ Reveal in Finder (or just Reveal)
from the contextual menu.* A folder should open with an item selected. Move the selected item to the Trash. You may be prompted for your administrator login password. Restart the computer and empty the Trash. Recreate your settings in the Sound preference pane.
*If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
Go ▹ Go to Folder...
from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
14. Reinstall OS X after backing up all data.
15. Make a "Genius" appointment at an Apple Store.

on the train). when I plug headphones in its great no probs.
Advice please! I don't want to send it back I'm halfway through my assignment.

I just realized I've never heard the internal speakers on my new iMac, I have always used good 2.1 speakers since I got my eMac years ago and the internals really sucked.
I was just curious, have you heard anybody elses built in iMac speakers and did they sound better than yours or the same? Maybe at the Apple Store?
I don't know, I just didn't know if they really improved them. Maybe other iMac users can chime in on internal speaker quality. The only reason I said all this was because you mentioned that headphones sound great, which is the same port that a set of external speakers would go.
Sorry to hear you had to send it back for that. Here's hoping you didn't have to send it in for what the speakers really do sound like.

No sound from internal speakers in HP Mini

i can't hear any sound from internal speakers although if i connect headphones or external speakers i can hear sound!

Hello @Landon3400 ,
Welcome to the HP Forums!
I understand your notebook only has sound, through your headphones.
Try updating the driver with the following download and tell me if it resolves the issue: IDT High-Definition (HD) Audio Driver.
Furthermore, check out this thread that has a lot of great suggestions for issues with no sound: Troubleshooting Guide: Audio does not Work after a Certain Period of Time and this document for no sound in Windows 8: No Sound from Speakers (Windows 8)
It would help to know which product and operating system you are using.
For information on finding your product and model numbers click here: How Do I Find My Model Number or Product Number?
To see which version of Windows you are using click here: Which Windows operating system am I running?
I look forward to your reply!
Let me know if this helps!
Please click the "Kudos, Thumbs Up" at the bottom of this post if you want to say "Thanks" for helping!

No sound from internal or external speakers

Imac 27" mid-2011 running Maverics 10.9.3 I'm not getting any sound from internal or ext. speakers. I can hear the startup sound when booting up.
System Preferences->Sound only shows Digital Out for OUTPUT and Output Volume is maxed and can't be adjusted. Mute is NOT checked.
I've done an SMC and PRAM reset with no change. I've tried multiple times plugging and unplugging the external speaker cable jack.
Any suggestions would be most welcome.

Hey krawfo,
Thanks for using Apple Support Communities.
Looks like you are not getting sound from your speakers. I see you have tried different things to try and resolve this. This article is a good resource for this issue.

Check to see if a red light is lit in the line-out port. If so, your Apple computer may need service.
Have a nice day,

Do you have any unknown devices in Device Manager with a yellow triangle and exclamation mark?
Are the Bootcamp drivers installed?
You should something similar to the following for Sound Devices, if the drivers are installed.

Sound icon disabled no sound from internal speakers

When I start my MacBook Pro I can hear the familiar "apple start" sound from the sepeakers. But about an hour ago the sound icon on the top bar is disabled (grey), no sound is coming from the computer speakers. In Settings > Sound, the volume bar is at max level, but also disabled. External speakers and headphones work fine.
What is this?

With nothing connected into the earphone jack, do you see a red glo inside the earphone jack?
If yes, then try insertting and removing an earphone plug, several times, to see if you can get the red glo to stop.
Else you might need to make an appointment with an Apple Approved Service Provider.

WNo Sound from Internal Microphone - Windows 8.1 Lync App on Lenovo Yoga 13

After upgrading from Windows 8 to 8.1 the microphone input in Lync ceased to work.
Lync correctly shows that I have both a webcam and microphone in my laptop, and both are turned on under Permissions.
I have updated all my drivers to latest available on Lenovo's website.
When I examine the microphone driver in the Device Manager, it shows that audio is being picked up and can properly route audio through to the laptops internal speakers.
The only app that appears to have a problem with the internal microphone is Lync. For example, the YouCam application properly captures both audio and video.
Any suggestions?
Windows 8.1 64bit
Lync (from app store)
Lenovo Yoga 13
The YouCam app can properly capture audio and video.
The YouCam app can properly capture audio and video.

Hi,
Are you able to make call using this Internal Microphone? I would like to confirm if the call can be established and there is no sound from Microphone.
Please check the Audio and Video Device in Lync client option. Please also select "Before I join meetings, ask me which audio device I want to use" in Phones option so that you can choose the correct audio device for call.

Loss of Sound from Internal Speakers

My PowerBook G4 DVI has lost it's ability to play any sound from it's internal speakers. A check of the Sound Output preferences in System Preferences shows that the sound is routed to Headphones, despite no headphones being plugged in. Partially plugging a headphone jack into the headphone socket (and jiggling it about a bit) results in the sound being routed to the internal speakers. Sound re-routes tot he headphones as soon as I remove the headphone jack.
Is this a hardware problem or has anyone else experienced this?

Welcome to the discussions Mark.
Very occasionally when I remove my headphones from the socket the PowerBook still thinks the headphones are plugged in and doesn't re-route the audio to the internal speakers. I find that plugging the headphones in and out again fixed the problem. I'm not sure whether it's a hardware or software issue (I suspect hardware), but you're not the only one to suffer from it.
Unless you're still under warranty, plugging in and out is the only solution I've come across
You could also post feedback to Apple about this issue using the link below. Apple won't respond to you (hey generally don't read these discussions), but since it is a bug of some sort, they should be made aware of it.

Sound from internal speakers keeps coming and going.

My internal speakers aren't working consistently. One second I hear sound and then the next I hear nothing. I checked "System Preferences > Sound > Output" and can see that the selected device keeps randomly switching from Internal Speakers to Digital Out to Headphones. Why is this happening, and how do I fix it?
Thx

1. Reset PRAM. http://support.apple.com/kb/PH14222
    Do this twice
2. Reset SMC.     http://support.apple.com/kb/HT3964
